The former X Factor judge will front the ITV show Boyzone At 20: No Matter What, according to Digital Spy.

It will feature the group singing some their greatest hits and some tracks from new album BZ20 in front of a live studio audience.

Dannii said: "I'm really looking forward to being back in the UK and hosting this show for some of the loveliest guys in pop. Twenty years of Boyzone, what an incredible career. It will be a night of pop music to remember."

Boyzone will discuss what life has been like during their career, as well as paying tribute to bandmate Stephen Gately, who died in 2009.

In a statement, the group said: "To have been together for 20 years is fantastic, and this is the perfect way for us to celebrate our milestone.

"We love performing in front of an audience and we can't wait to sing some of our classics once again, as well as offering our audiences something new."

Boyzone will also welcome former Spice Girl Mel C who will sing with them for a special version of No Matter What.

The group are on tour in November and December, and will release new album BZ20 on November 25.
